I would assert that the mere existence of every planet and every sun in the universe is evidence of gravity, not to mention their relative motions.
Sure .. define what you
mean by 'existence'. After all .. I have (and included lots of objective evidence supporting that definition).

Not all planets even have life forms, but they all experience gravity as the huygen's probe, and the mars landers clearly demonstrate and verified without a human mind ever touching the surface.
My dear Michael .. those probes were designed by human minds! And they carry telemetry and sensors designed to produce information which our minds can interpret. They followed trajectories predicted in advance by our mind's models used in describing our physics of 'gravity'.
No evidence of anything mind independence in any of that ..
Michael said:
That's funny.
Let me toss that right back at you and point out that regardless of what you believe, your "faith" that gravity is not independent of the human mind is badly misplaced.
Well, what's even funnier is that I (and the MDR hypothesis) never ruled out that gravity might be independent of human minds!
Read it again ..
here it is in its first form, and
again in its revised form. There's no faith in any of it .. its a
testable hypothesis!
Michael said:
Even if no life forms occured on this planet, this planet would still exist thanks to gravity, as would our sun, and every planet in our solar system.
I notice you freely using the words: 'planet', 'sun' and 'solar system' (and 'exist') to make your point .. Ever stopped to contemplate where the meanings of those words came from? Did
the meaning of those words even 'exist' before human minds invented them? Can you demonstrate the objective test which shows they did? The only way I can even contemplate the existence of those things in the first place is if they have that meaning. Without it, I wouldn't even have a clue about what you were talking about.
If there is no test which demonstrates that such meaning exists independently from our minds, then there we have it
yet again .. evidence of mind dependence ... and not evidence of
anything independent of a human mind.
Michael said:
I'm quite sure that there are *many* solar systems with no life forms in them at all, yet they have suns and planets none the less. Our moon experiences gravity at pretty much the expected amount as we verified when humans landed and walked on the moon.
Sure ... no disagreement there. The model you describe is objectively testable also. The model can also be tested for its dependence on a mind .. and it passes that test with flying colors because you, (a mind), are personally
'quite sure that there are *many* solar systems ..' (etc) ... more evidence of a mind model depicting what is real. No evidence of mind independence in that!
Michael said:
Somewhere in there you *must* accept these basis premises, otherwise cosmology theory and astronomy as a whole are pretty much irrelevant.
Certainly
not irrelevant! Those models are highly useful .. they predict, and their predictions are objectively testable. The outcomes of those tests then form the basis of science's objective reality.
There's no way I could ever call that
'irrelevant'!?!
